FURNACE-CHILL.

SPECIFICATION forming part of Letters Patent No. 511,851, dated January 2, 1894.

Serial No. 480,610- (No model.)

To to whom, it may concern.-

Be it known that we, ALEXANDER LAUGH- LIN, of Sewickley, and J OSEF REULEAUX, of Pittsburg, in the county of Allegheny, State of Pennsylvania, have invented a new and useful Improvement in Furnace- Chills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this [0 specification, in which- Figure 1 is a plan view of the casting or castings by which the bottom of the furnace is supported,- and a plan view of the cooling fines hereinafter described. Fig. 2 is a longitudinal medial section on the line 11-11 of Fig. 1. Fig. 3 is a vertical cross-section on the line III-III of Fig. 1, the bottom plate and chills being shown in section. Fig. 4 is a horizontal section through part of a furnace-bottom, showing the coolingflues on line IV. Figs. 5 and 6 are vertical cross-sec tions on the lines VV and VIVI of Figs. at and 5.

Like symbols of reference indicate like parts in each view.

Our invention is designed to improve the construction by increasing the durability of the dividing walls of metallurgical and other furnaces, and it consists in a furnace having a series of heating chambers and having longitudinal fines in the sides of the bottom which are open to the air and connect with cross-fines or chills in the bottom of the division walls.

It also consists in the construction and arrangement of parts as hereinafter more fully described and set forth in the claims.

In Fig. 5 of the drawings we show in section parts of a series of three adjacent heating-chambers 2, 2, of a metallurgical-furnace,

adapted principally for reheating steel ingots. 3, 3, are the bottoms of these chambers. The furnace bottom is supported by a metal plate '4, which may be made of an integral casting of any suitable metal, and is surrounded with chills, fines or channels 5, 5, which extend within the bridge-walls 7 and are open at the bottom and ends, and transverse flues, channels or chills 6, open at the bottom and c0m= municating at the ends with the flues or chills 5o 5. The ends of the longitudinal fines or chills preferably extend through the furnace walls, and communicate with the external air. The preferable form of the bottom-plates and the channels or chills 5 and 6 is shown 1n detail in Figs. 1, 2 and 3. By these means a continuous circulation of cool air around the bottom parts of the dividing walls of the heating or melting chambers is maintained through the fines or chills. The dividing walls are thus chilled and are prevented from rapid destruction by the action of the heated slag, &c.

The invention is applicable not only to heating-furnaces, but to crucible-furnaces and others of like construction.

Modifications may be made in the form and construction of the parts without variance from our invention, since That we claim is- 1. A furnace having a series of heating- 7o chambers, and having, at the sides of the bottoms thereof, longitudinal flues or chills, in combination with cross dues or chills in the bottom of the division walls and connecting the longitudinal flues or chills, said fines being open to afford a common circulation of air for the purposes above stated; substantially as described.

2. A furnace having a series of heating chambers, and having at the sides of the bot- 8o toms thereof a supporting-frame formed on its under side with longitudinal fines or chills, in combination with cross fines or chills in the bottoms of the division walls and connecting the longitudinal lines or chills, said fines being open to afford a circulation of air; substantially as and for the purposes described.

In testimony whereof we have hereunto set our hands.
